LP2982AIM5-3.3

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

LP2982AIM5-3.3 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply pin; the datasheet requires a capacitor of 1 µF or larger from this pin to ground.
2 GND power_in Ground reference pin for the regulator.
3 ON/OFF input Enable pin: driving it high enables the LDO and driving it low disables it, and it should be tied to VIN if unused.
4 BYPASS bidirectional Low-noise bypass pin; an external capacitor between this pin and ground reduces reference voltage noise.
5 VOUT power_out Regulator output; the datasheet requires a capacitor of 2.2 µF or larger from this pin to ground (nominal value for the new chip must be greater than 2.2 µF).
